Recent Developments in Benzoannelated Triquinacenes and Fenestranes

1 Results Introduction of functional groups at the frameworks of the centropolyindanes is a non-trivial task since the construction of the rigid and massive skeletons of,e.g.,tribenzotriquinacene and fenestrindane requires well-balanced synthesis strategies1,2].In the present contribution,some selected examples are presented for the recent multiple functionalization of tribenzotriquinacenes,such as compound 1,and fenestrindanes,such as compound 2,preformed in our laboratory.See Fig.1.
